Store a polynomial in non-symbolic language
by Yi Zhang
Sometimes one wants to store a polynomial in a non-symbolic language, such as Fotran or C. A easy way to achieve this is to take advantage of the isomorphism between polynomial space and space . Namely, we can build an array with entries as the coefficients of the polynomial to be stored. Furthermore, considering these coefficients are just the coordinates of the polynomial in the space spanned by the canonical basis ,,,, we can express the polynomial using any basis expansion.
